When I was young, my sister went missing. There was a terrible blizzard, yet she went out of her hutch and into the storm. I was the sin eater, so the people told me I must spend my life well if I died finding her. I followed her trail and found her when the storm cleared, on her knees, staring up at the aurora with tears in her eyes.
Soon, she gave birth. The people told me to erase the crime of the aurora by eating the sky-child. This was their mistake. I had been fed on the weaknesses of the people, but the sky-child was strong. After I have eaten the rest of the people, I will go out and find greater strengths to devour.
